My research is on 1) long-term ecological research of a regulated river (Nakdong River), 2) ecological mechanism of plankton blooms in a regulated river system, 3) food web dynamics in the flood-plain wetlands, 4) impact of aquatic invasive species, 5) scientific understanding of traditional knowledge and culture in the wetlands. My laboratory studies diverse taxa and wide-ranging issues in the study of aquatic ecosystems. As a national representative of SIL my main goal is to encourage the participation of Korean SIL members. I will also try to enhance capacity building of young limnologists by strengthening relationships with international research networks, knowledge sharing, and collaboration.
